Given numbers are 903,221,440,454

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 903,221,440,454 is 19932352440.

Find LCM of 903,221,440,454 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 903 x 221 x 220 x 227 = 19932352440

Therefore, the lowest common multiple of 903,221,440,454 is 19932352440.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

903 x 221 x 440 x 454 = 39864704880

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

903 : 1, 3, 7, 21, 43, 129, 301, 903

221 : 1, 13, 17, 221

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,221,440,454, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

221:13x 17

440:2x 2x 2x 5x 11

454:2x 227

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 39864704880/(1x2)

LCM = 39864704880/2

LCM = 19932352440

Thus, we can understand that the LCM of 903,221,440,454 is 19932352440.
